I'm planning on running a game where my players are going to become involved in some plots with vampires now the vampire in SR4 is ok but there isn't much flavor if you use only that vampire, so what I was thinking was either modifying SR4 to Storyteller or vice versa, I was wondering if anyone has any suggestions...

having played the old WoD games and a couple of incarnations of SR i have to say your best bet for something like this is to get a bunch of WtA and VtM players who like to play SR and have them help you convert using the Minds Eye Theatre rules for the entire world of darkness setting. Honestly it will probably end up playing more like your playing SR using VtM and WtA characters but thats really about as serious as anyone is probably gonna take this. I've been working a bit here and there using the WtA players guide to convert SR4 for convention play, but i'm really doing it just to frag with the majority of the local VtM players.
